. REFRIGERATOR DISPLAY CASE.

Application filed January 25, 1928. Serial No. 249,271. I

This invention relates to improvements in a refrigerator display case especially designed and constructed for use in drug stores or like establishments where it is desirable to display certain commodities which in order to be properly preserved must be kept at a properly cooled temperature.

This case is so designed and constructed as to properly function in such localities where the temperature is rather warm, such as for example the Southern States and tropical sections of the universe.

In this case I provide a certain cooling compartment the same being expressly constructed for the preservation of biological products which must at all times be kept at an even and cooling temperature, these products being in part, diphtheria antitoxin; tetanus antitoxin; antidysenteric serum; anti-anthrax serum; antimeningococcic serum; antipneumoccocic serum; antistreptococcic serum; rabies vaccine; bacterins serpbacterins; hay fever pollen extracts; tuberculins; smallpox vaccine; anthrax vaccine; blackleg vaccine; mallein; biological laboratory reagents pneumococcus; antibody solution; and others, in the display or shelf portion of the case such articles as candies and the like are displayed, as well as retained in a proper hardened state.

The case as constructed serves a double purpose, for displaying a commodity subject to destruction by too high a temperature,

preserving the same, as well as for properly products in a darkened cooling chamber within the same display case.

Figure 1, is a perspective view of my complete case as it appears when set up.

Figure 2, is a rear view of the case, showing the doors through which access may be had to the several compartments.

Figure 3, is a central vertical cross sectional view of the case.

Figure 4, is an enlarged vertical sectional view of the cooling compartment made use of.

Figure 5, is a detail perspective view of the cooling compartment with a part broken away and in section showing the detail of its construction, and the application of the biological product supporting trays therein.

In the general construction of my invention I provide a case composed preferably of a base section 6, a rear frame 7, two side walls 8, a top 9, and a slanting front 10. The frames comprising the side and front sections, are equipped with two lights of glass resonably spaced apart, so as to prevent sweating as well as toretain the proper cooling temperature within the case. 7 I i The rear section is divided into spaces each of Whichis equipped with a door 11 the same properly hinged, and e nipped with a latch 12 for completing a tight oint when closed.

Inside of the case, and approximately centrally located is a cooling compartment 13 composed preferably of a cabinet consistin of a front wall 14 and two side walls 15 the same being properly insulated, the rear side of the cabinet being open and registering against the rear wall or back frame of the case proper, and the opening is properly closed by the rear door 16, the frame above this door is also provided with a door 17 through which access may be had to the upper portion of the cabinet 13.

In the upper portion of the cabinet 13 is formed seated guide channels 19 for the reception of guide strips 20 secured to the sides of a tray 21 in which the cake of ice is placed for cooling the interior of the display case. The bottom of the tray is provided with a strip (1 bottom which permits the dripping to $11 into a dri pan 22 located beneath said tray, and the ripping is drained from the pan through the pipe 23.

In the cabinet beneath the drip pan, I provide a suitable number of trays 24 in which is to be placed the biological products, these trays are slidably mounted on angle rests 25 located on the inside of the cabinet walls 15.

The tray 21 being slidably mounted in the cabinet, permits the same to be pulled out through the upper door the tray with a fresh cake of ice.

In establishments where refrigerating machinery is handy, a coil may be installed on the top of the cabinet 13 thus dispensing with guide grooves 18 and in the sameare 17 when replenishing the use of ice, this arrangement is governed according to the locality in which the case is placed and used.

The essential feature of my invention is the placement of a cooling cabinet in a display case, and in which cabinet is placed and preserved biological products.

Having fully described my invention what I claim is:

1. A refrigerator display case, a transparent show case, cated within said case, a

comprising a cooling cabinet 10- tray mounted on the V cabinet in which is housed and preserved biological products, and trays located therein for the support of said product's.

' 3.' A case of the character described comprising in combination with a display show case, of a cabinet located therein, said cabinet constructed of proper insulating material, a

sliding tray forming the top of said cabinet,

a drip pan located beneath said tray, a partition supporting the drip pan, a drain plpe connected to the drip pan, and a plurality of trays slidably mounted in the cabinet and in which is supported biological products, substantially as specified.

4. A case of the character described, comprising a display show case, an insulated cabinet located therein and positioned centrally against the IGEtITHlll of said case, a drip pan mounted on the top of said cabinet, a tray slidably mounted above the drip pan, and trays located in the cabinet for supporting biologicalproducts, substantially as specified. In witness whereof, I have hereunto set my hand this 21st day of January, 1928.
